- Letters Patent No. 99,091, dated J ammry 25, 1870.

BASE-BURNING- STOVE.

The Schedule referred to in these LetteraPatent and making part of the same.

To all whom it may concern:

Be it known that I, J OHN H. KEYSER, of the city and county of New York, in the State of New York, have invented a newand useful Improvement in Stoves; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a front view of my improved stove.

Figure 2 is an antero-posterior section, vertically through the stove.

Figure 3 is a horizontal section through the stove, taken at the point x a: in fig. 1.

Figure 4 is an enlarged section, through the illuminating-section and its movable ring, and the fire-pot.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to improvements on surfaceburning or base-burning stoves; and

It consists-' First, in constructing an illuminating-section, with a circular perforated and adjustable ring, which ring is adapted to serve the twofold purpose of a ventilating-damper, for checking the draught, and of a means for exposing to view the light of the fire, as will be hereinafter explained.

Second, in combining in a stove the following elements, to wit, an open basket-grate and illuminating base-section, an illuminating-section surrounding the top of the said open basket-grate, and-expanded, to form a laterally-enlarged fire-chamber, and a fuelmagazine, arranged over said open basket-grate, and surrounded by an ascending draught-passage, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I will explain its construction and operation.

In the accompanying drawings- A represents the base-section of the stove B, the section which surrounds the fire-pot or open basket-grate J C is an illuminating-section, arranged on top of the section B, and enclosing the fire-chamber; and

E is-the top section, from the top of which the magazine G is suspended,

The section B is constructed with a very large opening, 1), through its front side, which opening is closed by doors filled with mica, so as to expose to view the light of the fire, and produce what I term an open fire-stove. Y

The opening b is made so as to expose to view the entire front of the fire-basket or open pot J, which latter is suspended centrally within the section B, from the diaphragm P.

The section D is made bulging, as shown in the drawings, for the purpose of forming a laterally-enlarged fire-chamber above the diaphragm P and the upper terminus of this section is constructed, first, to receive the cylindrical top section; second, tocOntract the passage, for the ascentof the products, immediately above the level of the fire; and, third, to adapt its upper portion to receive the ring D.

This section 0 affords a handsome ornament to the stove; and, by means of the windows 0 through it, which should be closed by mica plates, it is made to serve as an illuminatingsection, directing the rays of light from the fire-chamber outwardly, and upwardly, and downwardly.

Above the mica-light windows 0, of section 0, holes 0 are made throughthis section entirely around it; and in the same horizontal plane as the holes, corresponding holes are made through the movable ring D, so that when holes 0 and d are brought to register with each other, air will be admitted through. them into the combustion-chamber at the upper contracted end thereof. At the same time light will be radiated into the room through these holes.

By its convexity, the section 0 is admirably adapted to serve as a support for the ring D, which latter is provided with a handle or knob, by which it can be moved, and also with means for regulating the amount of movement required to give it for opening or shutting, more or less, or completely, the holes 0.

The top section E rises from section 0 a suitable height, and is covered. 7

The magazine G may be suspended from the top of the section E,-or sustained in any other suitable manner.

This magazine is provided with a cover, f, and is used for containing coal to be supplied to the open fire-pot or basket J.

I am aware that circular registers have been applied to stoves before my invention, but I am not aware that a circular perforated ring has before'been known or used, which was arranged above the firechamber, an illuminating-section, and at the contracted upperportion of such a section, whereby air could be admitted inwardly and downwardly upon the fire, and whereby such perforated ring was adapted for purposes of illumination.

Another advantage obtained by the use of the perforated adjustable ring D, arranged as described, is, that cool air is caused to impinge directly-upon the lower fire-exposed part of the reservoir G, which will,

to a great degree, prevent this reservoir from rapidly burning out.

Having described my invention,

That I claim as new, and desire to secure by Letters Patent, isv 1, The circularly-adjustable perforated ring D, ap-

plied to the upper portion of the-perforated illuminating-section O, substantially as described.

2. The combination of the open section B, basket or open pot J, illuminating-section O, and fuel-magazine G, substantially as described.

' 3. The bulging section 0, constructed with windowopenings 0, and perforations e, substantially as described.
